Technical field

The present invention relates to communication system.

Background technology

In order to support to transmit different service (such as voice data or video data) to the different recipients residing in such as country variant, efficient communication network is required.Such as, at " ControlServersintheCoreNetwork ", EricssonReviewNo.4, in 2000, describe efficient horizontal slice framework.As example, introduce in such as 3GPP (third generation partner program) specification and include 3 different layers with the layered network architecture issued: application layer, network control layer and articulamentum.Application layer supports end-user application, and can realize application layer in mobile station in a network or application server.Application layer can be mutual with Internet via one group of application programming interfaces (API), and these application programming interfaces (API) make it possible to design and realize different services and application.The communication service of different type network is such as crossed in network control layer support, the circuit commutative field network of these different types of networks e.g. based on GSM standard use such as ISDN correlation technique or use the packet switching network of such as GPRS technology.Articulamentum is can be via such as voice, data and the transport layer of any kind of service of transmission of multimedia streams.

According to UMTS (UMTS) technology, key-course can include the mobile switching centre (MSC) processing the key-course function on the interface between access network and core net.Communication between access network and MSC server can perform based on RANAP message (wireless access network application protocol).Network control layer according to UMTS technology can also include the transmission switching centre (TSC) of the communication of (such as, ISDN (integrated services digital network) or PSTN (PSTN)) between higher management net and another network.MSC and TSC can communicate with the respective media gateway (MGW) being arranged in articulamentum for managing data transmission or mobile MGW (M-MGW) via gateway control protocol (GCP) message.Generally, MGW receives data via access network from communication entity (such as, mobile station or application server), and such as ATM (asynchronous transfer mode) stream compression is changed to IP (Internet protocol) data stream, for transmission further.

Provided for crossing over fixing and another emerging communication technology of Mobile Access Network transmission multimedia service by IP Multimedia System (IMS) technology.The network architecture according to IMS includes: service layer, corresponding with aforementioned applications layer；Control and articulamentum, corresponding with aforementioned network key-course；And Access Layer, corresponding with aforementioned articulamentum.Specifically, controlling and articulamentum can include CSCF (CSCF), CSCF is formed and is used for specifying the central entity of SIP signaling (SIP: Session initiation Protocol).Controlling and articulamentum also includes MGCF (MGCF), MGCF communicates with CSCF via sip message, and uses the WMG message according to the most H.248 agreement and the WMG communication being arranged in Access Layer.Control and articulamentum can also include that MRF (media resource function), MRF provide media services the most in the home network.

Another emerging communication technology is the evolved packet system (EPS) defined by 3GPP normal structure.One of communication technology disposed in the context of EPS is LTE access technology (LTE: Long Term Evolution).EPS includes that MME (mobile management entity), MME define the controlled entity being applicable to signaling, and selects the gateway (SGW) routeing user data packets and forwarding.MME and SGW is a part of evolution block core (EPC), and evolution block core (EPC) includes other unit, such as SGSN (service GPRS support entity) or PGW (grouped data network gateway).

Aforementioned communications techniques is carried out example with reference in the case of, substantial amounts of network entity can process and the user-dependent and a large number of users signal of communication including payload and signalling loads respectively.But, some in these network entities are mainly affected by the process that signalling loads is relevant with signalling loads, and other entities relate generally to the process that payload is relevant with payload.Therefore, when the network entity mainly processing signalling loads is also equipped with the ability processing payload, it may not be possible to make full use of available network resource efficiently.

Detailed description of the invention

In order to network entity targeting scheme is described, it is possible to use the EPS mobile communication system defined by 3GPP normal structure is as example.According to EPS mobile communication system, the network entity (network gateway that is that such as, process the telex network including payload and signalling loads and that can be distributed by location and/or repositioning process or other nodes of communication network) of some can process the user of some.But, some entities in these entities are only affected by with each user-dependent signaling procedure；And other entities perform to carry payload and/or exchange and/or route, relatively limited by being affected from signaling procedure.Pay close attention to the principal entities defined by EPC framework, such that it is able to according to the process impact caused by signalling loads intensive user signal of communication and payload intensive user signal of communication, classified by network entity.Thus, if signaling impact affects more than payload for network entity, then user communications signals can be defined as signalling loads intensive.Relatively, if payload impact affects more than signaling for network entity, then user communications signals can be defined as payload intensive, as exemplary summary in following table.

Above-mentioned classification is the ordinary circumstance as example, and can also be affected by the parameter relevant to standard, such as, in the case of SGSN, affected by the deployment in the direct tunnel of 3G (3GDT).The use of 3GDT can reduce the payload impact on SGSN, this by upper table classification " in " reflected, depending on being assigned to the quality using the user of 3GDT, the impact of GGSN may be risen by signaling simultaneously.Another parameter is subscriber (i.e. user) behavior.Thus, some users are that payload is intensive, and have the signalling loads of minor proportion, and the signalling loads that other users create can be higher than the ratio of payload.Thus, such as distribute to payload intensive user process, for payload, the network entity being optimized, it is provided that for efficiently utilizing the efficient means of available network resource.In order to obtain signalling loads optimization and/or the network entity of payload optimization, can realize being optimized to existing SGW and PGW for the signaling special ratios (that is, certain loads ratio) to payload capacity.This optimization can be flexibly, and it can be by such as using different Card Type, different hardware or different software to realize for signaling with payload.Furthermore, it is possible to adjustment network entity, can configure according to the particular user characteristic relevant to signalling loads or payload.As example, in order to support high payload, the network entity of payload optimization may require the backboard/power board (payload capacity that its impact is supported) optimized, if and configure entity mainly for signaling, then this backboard/power board represents the base cost becoming overhead simultaneously.Relatively, high signaling capacity may from and the HW (hardware) that realizes of payload intensity require that different HW requires to be associated so that use public HW to mean unnecessary HW cost generally for the situation of plank payload to be used for for both.This may make to seem more more expensive than configuration based on HW on the flexible nature based on SW between signaling and payload capacity.Therefore, if overall user behavior changes over time due to new application or the deployment of commerce model, then the hardware based rebalancing between signaling and payload capacity might imply that for potential very important OPEX (operation cost) cost increasing number destination entity.Fortunately, for signalling loads, certain ratio of payload can be optimized network entity (such as SGW and PGW), the motility of this optimization is probably limited.This network entity can be specifically designed to process payload intensive user signal of communication or signalling loads intensive user signal of communication.

Term " payload " referred to herein generally refers to real data, or loading (cargo), and payload can be carried in packet or other units of transfer, and this packet or other transmission units can also include one or more header.As example, payload can include the information sending to user or sending from user.Generally, payload does not include signalling loads.Signalling loads by the data needed for payload is sent to its destination or can be made up of the data being used for appropriately processing payload.Signalling loads is also sometimes referred to as overhead data, and generally can find in the header.

Such as according to the definition of certain communication protocol, the payload of user communications signals can be relative to each other with signalling loads.Any instruction accordingly, with respect to payload or signalling loads can make it possible to derive the information that the duty factor between payload to signalling loads is relevant simultaneously.This information can be carried by load attribute.Load attribute instruction duty factor between payload and signalling loads.This load attribute can be following at least one: user's classification, payload tolerance, signalling loads tolerance and duty factor (business such as constructed according to payload amount and signalling loads amount).

Referred to herein can be one below for processing the network entity of user communications signals: gateway (SGW), WMG (MGW) and grouped data network gateway (PGW).

Additionally, the network controlling entity of the communication for controlling user referred to herein can be one of following entity: MME (mobile management entity), MSC (mobile switching centre) or SGSN (Serving GPRS Support Node) and MGCF (MGCF).

Term " transmitter " referred to herein and " receiver " can represent the entity that can send/receive signal from/to communication network.But, these terms can also represent and be employed to the protocol entity that is associated with the protocol layer that Peer is in communication with each other.

Fig. 1 shows the embodiment of communication system, and this communication system includes user subject (UE) 101, and UE101 is arranged through communication network 103 and communicates.As example, communication system also includes access node 105, and it communicates with network controlling entity 107 (NCE).As example, access node 105 can be evolution NodeB (eNodeB).Communication system can also include that central data store 109, central data store 109 can be disposed in home subscriber servers (HSS).Communication system can also include network entity 111 and network entity 113, and network entity 111 can be that payload optimizes gateway (GW (P)), and network entity 113 can be that signalling loads optimizes gateway (GW (S)).

Network entity position fixing process when embodiment shown in Fig. 1 demonstrates in network attachment (attach), wherein, in step 1a, user subject 101 is attached to communication network 103 via accessing entity 105.In step 1b, access entity 105 and attachment request is transmitted to network controlling entity 107, network entity 107 can signal this attachment request to central data store 109 in step 1c, and central data store 109 can be responded with the load attribute of such as instruction payload intensive communication signal (P) in step 2.Network controlling entity 107 can indicate network entity to position to access entity 105 in step 3a, and in step 3b, user subject 101 is navigated to the payload for payload intensive user communication is optimized and optimizes network entity 111, and delocalization is to the network entity 113 being optimized for signalling loads intensive user communication.The most in step 4, via accessing entity 105 and selected network entity 111, one or more communication entities not shown in Fig. 1 (at communication network 103 interiorly or exteriorly) and/or transmit by the user communications signals shown in dotted line to the one or more communication entity.

Fig. 2 shows the embodiment of communication system.Different from the embodiment shown in Fig. 1, user communications signals can be that signalling loads is intensive so that the attachment of step 1c can be asked to be responded with the load attribute that instruction user communications signals is signalling loads intensive (S) by central data store 109 in step 2.Afterwards, in step 3a, network controlling entity 107 indicates network entity to position to accessing entity 105, and in step 3b, positions the network entity 113 being used for processing user communications signals.Afterwards, in step 4, via accessing entity 105 and selected network entity 113, from the one or more communication entities (at communication network 103 interiorly or exteriorly) not shown in Fig. 2 and/or to the transmission of the one or more communication entity by Fig. 2 signalling loads intensive user signal of communication shown in phantom.

In Fig. 3 is to 7, demonstrates the network entity repositioning process in communication system as illustrated in fig. 1 and 2, which form the embodiment of network entity position fixing process.From the beginning of Fig. 3, user subject 101 communicates via the one or more communication entities (at communication network 103 interiorly or exteriorly) accessed not shown in the network entity 113 that optimizes with signalling loads of entity 105 and Fig. 3 to 7.See Fig. 4, according to scene a), network communications entity 107 can receive load attribute from central data store 109, it is that signalling loads is intensive that the instruction of this load attribute is derived from the user communications signals of user subject 101, and this can be triggered by the trigger event in central data store 109 or network controlling entity 107.In latter case, shown in dotted line, network controlling entity 107 can ask load attribute to central data store 109, and it can need not the trigger event in the case of the first.Trigger event can e.g. particular moment or the position of user subject 101.

But, according to the scene b) shown in Fig. 4, can be that the intensive load attribute of payload be sent to network controlling entity 107 by instruction user communications signals by network entity 113, such as ratio between payload and signalling loads or payload tolerance with instruction.In the later case, network controlling entity 107 may be it needs to be determined that signalling loads, to determine the payload ratio to signalling loads.As example, payload can be more than or equal to threshold value to the ratio of signalling loads, such as 50%, instruction user communications signals is that payload is intensive, this can trigger the network entity 111 that network controlling entity 107 selects payload to optimize, and initiates the network entity repositioning process of the network entity 111 optimized from the network entity 113 that signalling loads optimizes to payload.

As shown in Figure 5, network controlling entity 107 can send re-positioning request to network entity 111 and 113, and send re-positioning request to accessing entity 105, so that user communications signals is redirected (i.e., discharge from be presently processing user user communications signals current network entity (i.e., if Fig. 3 is to the network entity 113 shown in 5) the user communications signals of user, and the user communications signals of user is distributed to selected network entity (network entity 111 the most as shown in Figures 6 and 7)) network entity 111 that optimizes to payload is for communication further, as shown in Figures 6 and 7.

According to embodiment, it is possible to use GRP echo request or response message (it is specific that it can not be user) send load attribute.But, load attribute can be carried by privately owned extension IE (information unit), this privately owned extension IE can include the identifier of user, such as one of IMSI (International Mobile Subscriber mark) or S11TEID or IMEI (International Mobile Station Equipment Identity).

In order to allow the network entity 111 of payload optimization such as to unload (i.e. by signalling loads intensive user, reorientation) to signalling loads optimize network entity 113, or act in a diametrically opposite way, network entity 111 can such as use the existing GRP message on S11 interface to send the information about it to network controlling entity 107.In the case of understanding or not knowing about the feature (figure) of the signalling loads dense degree reflecting user, this can perform as the request for unloading user；Or can perform as " neutral (the neutral) " feature about signaling/payload closeness, leave network controlling entity 107 determines how to react it for.

In order to determine whether to send load attribute, it is possible to use send a threshold value of load attribute or different threshold value from network entity 111,113 to network controlling entity 107 for triggering.However, it is possible to send load attribute all the time for each user so that network controlling entity 107 can be determined that deferring to which bar standard comes trigger re-positioning or position fixing process.In this case, it is not necessary to threshold value, present threshold value can such as be omitted.

According to embodiment, threshold value can depend on or relate to network entity load rather than depend on and user-dependent parameter.As example, network entity 111,113, when close to the restriction of its signaling capacity, can send the user-dependent information maximum with signalling loads closeness to network controlling entity 107, and it can trigger or initiate their reorientation.If it is the most not by a long chalk that network entity 111,113 loads restriction with it, then network entity 111,113 can no matter active user's (that is, signal of communication of those users) signalling loads dense degree how, all suppress any information of transmission.

According to embodiment, the distribution (such as reorientation) of the user that the user of signalling loads optimization network entity (such as network entity) optimizes network entity (such as network entity) relative to payload can be based on implemented below:

As example, function in network entity 111,113 or monitor that entity can monitor the behavior of each user using it, and based on the most configurable threshold value and/or standard, can notify that the payload of user has how intensive or user in such as one configurable time period payload how intensive to have to the network controlling entity 107 being connected with user.Thus, it is provided that for the enhancing of S11 and S4 interface, enabling to transmit this information from network entity 111,113 to network controlling entity 107, wherein this information defines the embodiment of load attribute.As example, this enhancing can in existing message the GTPIE of " privately owned extension " type so that it does not require any standardization, keeps agreement and interface compatible with 3GPP simultaneously.

Another implementation may relate to the function on network controlling entity 107, it is based on from this information of network entity 111,113 and other configurable parameters, network entity repositioning process can be triggered, user to be moved to the network entity 113 providing service to same services region from such as network entity 111.As example, network entity repositioning process can be the standardisation process according to such as 3GPP standard.

According to embodiment, network controlling entity 107 can trigger network entity reorientation by one of procedure below according to 3GPPTS23.401 standard:

-there is the tracking area update process that service GW changes；And/or

-there is the switching based on X2 servicing GW reorientation；And/or

-switching based on S1.

Above-mentioned realization can permit compliance with the realization of 3GPP, because can be in the case of completely without changing, the mode specified in strict accordance with 3GPP standard reuses above-mentioned realization.The implementation of network controlling entity 107 can be depended on so that standard compliance can be not limited for triggering the condition of the change of current service GW.

According to embodiment, network controlling entity 107 can wait the next triggering to normal " tracking area update ", " switching based on X2 " or " switching based on S1 ", then can select the modification of " there is service GW change " rather than select the modification changed without service GW.In addition, even if (the most i.e., originally) network entity 111,113 still can use, it can also happen that service GW changes, such as such that regardless of way of realization as herein described how, may be implemented in the interoperability of any realization of " new network entity " in terms of 3GPP accordance.

Another function can be the central data store 109 on network, and central data store 109 is such as on network controlling entity 107 or in HSS, in central data store 109, can such as store user's classification of the embodiment forming load attribute.As example, entity 107 can be network controlled and send user's classification to HSS.User's classification based on storage, when having adhered to or PDN connects activation, and for the network entity reorientation triggered by change or other reasons unrelated to the invention of network entity coverage, can be assigned to the network entity of right type by user.

According to embodiment, network controlling entity 107 can also store and include such as with user (i.e., the user communications signals of this user) signalling loads or the relevant information of the dense degree of payload at interior load attribute, make can also when such as eUTRAN (evolution UMTS Terrestrial radio access network) adheres to, PDN connect when activating or when combining with the network entity reorientation triggered by the change of coverage or other reasons, user is directly assigned to the network entity 111,113 of suitable type.Thus, it may be considered that implementations below:

Load attribute can be locally stored in local storage by network controlling entity 107, or intensively stores in central memory.During the network entity reorientation triggered by any one occurrence in one group of event defined, or only in the case of attachment in the future or PDN connect and activate use identical network controlled entity 107, it is possible to use locally stored scheme.Central memory scheme in such as HSS or in application-specific entity provides and is conducted interviews by the multiple network controlling entity 107 in network.

According to embodiment, positioning or the supplementary or replacement of repositioning process as triggering network entity, network controlling entity 107 can store load attribute.The two action can perform independently of one another.According to embodiment, can only perform one of the two action.According to another embodiment, only storage function can use, and wherein, this information is used for attachment or PDN connects activation and can reduce the signaling consumption of complementary network entity reorientation.

According to embodiment, the central data store 109 in HSS can have the extension of S6a interface, and it is similar to can be by S11 interface for sending the usage of the privately owned extension IE of load attribute.

When being released in the connection accessed between entity 105 (such as eNodeB) and network entity 111,113, can perform S1 carrying release, it is the signaling manipulation realized according to some network entities.As example, when processing the user of such as network entity coverage or significant percentage of static or Hypomobility,-relevant the loading and compared with the memory footprint of every user, can be considered as less by the signalling loads relevant to mobility on network entity 111,113 of release is set up with carrying.

As example, measurement for the dense degree of the signalling loads relative efficiency load of specific user can be performed by measuring the characteristic of the payload that (that is, the S1 carrying in pairing is set up between release) sends during the life-span that each S1 carries by network entity 111,113.According to embodiment, mobility signaling can also be ignored in this aspect.The result measured can be the tolerance that load attribute maybe can derive load attribute.

According to embodiment, if network controlling entity 107 participates in some or all S1 carrying discharges/set up process and all mobile process, network controlling entity 107 may have the information of the signalling loads dense degree about user's (that is, user communications signals of this user).This is equally applicable to SGSN and RAB release.Network controlling entity 107 can also have about carrying have been set up information how long, even if making network entity by only transport payload, it can also calculate such as average load ratio, but directly providing duty factor is favourable for simplifying the realization of network controlling entity 107.

According to embodiment, network entity 111,113 can use load attribute to notify that user classifies to network controlling entity 107, and alternatively, use the such as privately owned extension IE in one of following message to come indication signaling load and/or payload usage amount: down link data notice and/or amendment carry response and/or release access bearer response.It is thus possible to send load attribute in being used for the specific fields sending in the transmission frame of above-mentioned message.

According to embodiment, network entity 111,113 can also add privately owned extension to other message.For example, it is possible in the case of the least on realization impact, allow it support all possible message.Message listed above is to be limited to change the example of possible the message in the case of the fewest message by realizing changing, because they relate to S1-U carrying foundation or release process, described process is the potential triggering for scheme proposed by the invention.

According to embodiment, it is also possible to piggyback load attribute in the GTP message sent for other purposes.It is possible in order to this purpose triggers explicit message, but optional.

Next, with reference to Fig. 8 to 13 describe network entity, network controlling entity, for distributing the corresponding method of network entity and for processing other embodiments of the corresponding method of user communications signals.

Fig. 8 shows the figure of the method distributing the network entity for the user communications signals processing user.The method includes: obtain the load attribute of 801 instructions duty factor between payload and signalling loads；803 network entities are selected based on this load attribute；And initiate 105 position fixing processs or reorientation, to be used for processing user communications signals by selected network entity distribution.In order to select network entity, the network address of such as network entity or the network assumed name of network entity can be selected.

According to embodiment, obtain 801 load attributes can include following at least one: receive load attribute by communication network from central data store, load attribute is retrieved from internal data memory, and/or produce load attribute, or retrieval load attribute or process load attribute after receipt based on the information retrieving or receiving.Central data store can pass through communication network access.As example, central data store may be located in home subscriber servers (HSS).Alternatively or additionally, load attribute can be stored in the internal data memory being positioned in network controlling entity, and this network controlling entity can initiate network entity position fixing process.

According to embodiment, load attribute be following at least one: user classifies, and the user communications signals of instruction user is that signalling loads is intensive or payload intensive；The payload tolerance of payload；The signalling loads tolerance of signalling loads；And the duty factor between the payload tolerance and the signalling loads tolerance of signalling loads of payload.

User's classification can include that indicating user communications signals is that signalling loads is intensive or the label that payload is intensive.User's classification also can indicate that user communications signals on the whole, be that signalling loads is intensive or payload is intensive generally or within a time period or on particular moment.Thus, it is possible to instruction duty factor.Correspondingly, the payload tolerance of payload indicates respectively duty factor, because these tolerance can be relative to each other with the signalling loads tolerance of signalling loads.Term " is measured " and can be related to quantity or ratio.

According to embodiment, it is thus achieved that 801 load attributes may include that and receive load attribute from the current network entity of currently processed user communications signals.Load attribute can be received by the network controlling entity that can initiate network entity repositioning process, and this network entity repositioning process defines the embodiment of network entity position fixing process.If network entity to be positioned is gateway, then network entity position fixing process can be network gateway position fixing process.Accordingly, network entity repositioning process can be gateway repositioning process.

According to embodiment, load attribute can include effective degree of loading amount and signalling loads tolerance, wherein, it is thus achieved that 801 load attributes also include: is correlated with, the payload received tolerance and the signalling loads tolerance received to determine duty factor.In order to by payload tolerance and signalling loads tolerance be correlated with, can such as with payload tolerance divided by signalling loads measure, or vice versa as the same.

According to embodiment, load attribute can include that signalling loads is measured, wherein, it is thus achieved that 801 load attributes also include: based on signalling loads tolerance determine payload payload tolerance, and by signalling loads tolerance and determined by payload tolerance be correlated with.In order to determine the payload tolerance of payload based on signalling loads tolerance, can such as make full use of the relation between payload tolerance and signalling loads tolerance prestored.

According to embodiment, network entity position fixing process can be initiated in step 805, join selected network entity with the user subject access communications network time-division in transmission user communications signals.As example, network entity position fixing process can be initiated when user subject attempts access communications network first.

According to embodiment, network entity position fixing process can be initiated in step 805, so that user communications signals is relocated to selected network entity from the current network entity of currently processed user communications signals, and wherein, initiate 805 network entity position fixing processs to include: from the user communications signals of the current network entity releasing user of the user communications signals being presently processing user, and/or the user communications signals of user is distributed to selected network entity.It is thus possible to user communications signals is redirected to the selected network entity that can may more efficiently process user communications signals from current network entity.

According to embodiment, network entity position fixing process could be for being relocated to user communications signals from the current network entity being presently processing user communications signals the repositioning process of selected network entity, and wherein, only determining that selected network entity and current network entity just initiate position fixing process in the case of being heterogeneous networks entity.It is different to determine current network entity and selected network entity, such as, can accord with the network entity identifier of the network address of comparing cell entity or any other type.

According to embodiment, initiate 805 network entity position fixing processs and may include that the network controlling entity to being able to carry out network entity position fixing process sends load attribute.As example, load attribute can be sent to network controlling entity by the current network entity processing user communications signals, and such as to ask network entity repositioning process, this network entity repositioning process forms an embodiment of network entity position fixing process.However, it is possible to such as send load attribute from the central data store of HSS.

According to embodiment, the method can also include: based on load attribute, it is determined whether initiates network entity position fixing process.In order to determine whether to initiate network entity position fixing process, can such as consider that complexity metric, such as this complexity metric such as indicate and user communications signals is redirected to the network cost that selected network entity is associated.Network cost can be determined by the following: the offered load of the present load that additional overhead, available bandwidth or the selected network entity being associated with additional signaling processes or the such as process load on involved network entity etc and the load of the link between these entities related to.

According to embodiment, the method can also include: in the case of not initiating 805 position fixing processs, stores load attribute in such as inside or central data store.It is thus possible to monitor load attribute in special time period, to avoid such as time in the case of varying load the unnecessary redirection to user communications signals.

According to embodiment, 803 network entities are selected to may include that if load attribute instruction user communications signals is payload intensity, payload is then selected to optimize network entity as selected network entity, if or load attribute instruction user communications signals is that signalling loads is intensive, then selecting signalling loads to optimize network entity as selected network entity.In order to select payload to optimize network entity or signalling loads optimization network entity, it is provided that look-up table, in a lookup table network entity is characterized as that payload optimizes or signalling loads optimization.

According to embodiment, the method can also include: determines average load attribute by being averaging the load attribute of multiple acquisitions, and selects network entity based on average load attribute.In order to the load attribute of multiple acquisitions is averaging, can be by load attribute summation the number divided by the load attribute obtained.It is weighted in addition it is possible to use such as forget (forgetting) factor pair load attribute, the impact average on present load attribute to reduce older (such as, expired) load attribute.

According to embodiment, network entity position fixing process can be network controlled entity and perform.

Fig. 9 shows the block diagram of the method for the user communications signals for processing user.The method includes: the user communications signals that transmission 901 is associated with signalling loads and payload, 903 load attributes are determined based on user communications signals, and send 905 load attributes to network controlling entity, this network controlling entity can initiate network entity position fixing process (such as, network entity repositioning process) based on load attribute.

The method can also comprise determining that whether load attribute meets threshold criteria.Thus, as example, load attribute can be compared with threshold value (one or more threshold value).If load attribute is less than threshold value, if or load attribute is higher than threshold value, if or load attribute is equal to threshold value, then can meet threshold criteria.Additionally, in order to whether proof load attribute meets threshold criteria, enumerator can be increased or decreased for load attribute.

According to embodiment, the load attribute mentioned in conjunction with the embodiment of Fig. 9 can be any load attribute referred to herein.As example, load attribute can include following at least one: the payload of payload tolerance, the user communications signals of instruction user are that signalling loads is intensive or payload is intensive user's classification, the signalling loads tolerance of signalling loads and the payload in payload measure the duty factor between the signalling loads tolerance of signalling loads.

According to embodiment, the method can also include: if load attribute meets threshold criteria, then send 905 load attributes to network controlling entity.

According to embodiment, the method may include that to be optimized if the network entity of currently processed user communications signals processes for payload, then, when load attribute instruction user communications signals is signalling loads intensity, send 905 load attributes；If or the network entity of currently processed user communications signals processes for signalling loads and is optimized, then, when load attribute instruction user communications signals is payload intensity, send 905 load attributes.As example, only can just send load attribute in the case of user communications signals is signalling loads intensity and current network entity is to be optimized for payload process.Accordingly, can only user communications signals be intensive and currently processed user communications signals the network entity of payload be process for signalling loads be optimized in the case of just transmission load attribute.Can be by the ratio of signalling loads with payload be compared with threshold value, performing about signal of communication is that payload is intensive or the determination that signalling loads is intensive.

According to embodiment, load attribute can be sent, change the network entity for processing user communications signals with request.Thus, only send load attribute and may indicate that such as performing network entity selects and then perform network entity repositioning process.

According to embodiment, can via network interface (specifically, via S4 interface or S11 interface) or in step 905, send load attribute to network controlling entity via control protocol (specifically, via GTP (GTP:GPRS tunneling protocol) or GCP (gateway protocol)).It is thus possible to use existing interface or protocol message send or receive load attribute.

According to embodiment, load attribute can be sent in the extended field of transmission message frame.As example, the corresponding communication standard according to transmission load attribute institute foundation that load attribute can be disposed in transmission message frame is not yet in the field of other signaling.But, in order to send load attribute, transmission message frame can be strengthened by extended field.Load attribute can be numeral or character or numeric string or character string.

As example, it is possible to achieve network entity and/or network controlling entity as described herein so that user communications signals or carrying level GTP message can carry the privately owned extension IE defined according to principle described herein.It is used for carrying load attribute however, it is also possible to define new message.This message can be GTP message, wherein it is possible to use GTP header.But, even the message not meeting GTP grammer can be used for sending load attribute.

Figure 10 shows that the EPS as example carries timeline, wherein, moment (t0, t2, t4) represent S1 carrying to set up, moment (t1, t3, t5) represent S1 carrying release, and P0, P1 and P2 represent the amount of the payload sent between the adjacent foundation and release of carrying.As example, Figure 10 relates to following layout, and wherein, MME defines the embodiment of network controlling entity, and SGW defines the embodiment of network entity.In addition to payload, it is also possible to send the signalling loads the most explicitly illustrated.

With reference to Figure 10, MME and SGW (according to the definition as logic 3GPP entity of himself, and usually respectively as network controlling entity and the illustrated examples of network entity) can have the access right with its user-dependent load attribute processed.In order to collect the information relevant to load attribute, dependent event can be monitored, and can store, safeguard and capture described information efficiently.About SGW, load attribute can include signalling loads information, such as set up to carrying and the relevant signaling of release, payload information, any tolerance that maybe can be obtained by supervision user plane packets, as bandwidth, packet size, business including payload and/or signalling loads sudden etc..About MME, this information can include all signalling loads, not only includes setting up relevant signalling loads to carrying, also includes relevant to mobility or relevant with service quality (but not requiring that carrying changes) signalling loads.For the SGW that user is distributed to suitable type efficiently as described herein, load attribute can be payload feature and the relation of the signalling loads relevant to carrying.As example, but the SGW ignorant signalling loads information that MME knows can increase certain values, but is only limitted to limited degree, because the ignorant any signaling information of SGW does not have any impact to the signaling capacity of SGW really according to definition.

As example, SGW can collect user specific information, and uses load attribute to transmit this user specific information to MME, can by load attribute with such as can configure threshold value and compare, to trigger the communication for MME.Load attribute may include that setting up the payload amount of transmission from last S1 carrying or setting up the payload amount of transmission from such as last EPS carrying as shown in Figure 10, or the average throughput set up from last radio bearer or EPS carrying or the S1 of last given number carry set up and S1 carrying release between mean effective load.In addition, weighted average can be performed, this weighted average is set up deenergized period in view of the carrying in some or all of past, but relatively big to the weight in nearest cycle, or the S1 of last given number carry set up and S1 carrying release between average throughput.Furthermore, it is possible to perform such weighted average, this weighted average is set up deenergized period in view of the carrying in whole past, but bigger to nearest cycle weight.

According to embodiment, the calculating to load attribute, the such as calculating of the duty factor between process user's payload and signalling loads can be processed at SGW.Thus, if SGW has the access right to the data relevant to the packet of each and all payload potentially, then can realize the bigger motility relevant to obtainable data, wherein, MME can only obtain the summary information forming load attribute from SGW.It is furthermore possible to also provide for optimizing the more probabilities realized, such as some parts code directly being included, payload processes in function.A part based on the life-span that the EPS shown in Figure 10 carries can demonstrate the motility that this SGW realizes.Carry (such as at EPS, EPS carrying such as 3GPPTS23.401 definition, it can be the end-to-end carrying from UE to PDN-GW) life-span in, when predict there is no business in the near future time, its S1-U part can be discharged by SGW and eNodeB, and the most again set up this S1-U part.In the scope of the present disclosure, according to embodiment, this can be referred to as " carrying is set up " and " carrying release ", and relative to having more long-life EPS carrying, it can refer to that S1 carries.Thus, eNodeB can form another embodiment of network controlling entity.

Realize about SGW, still with reference to Figure 10, it is possible to calculate the numerous not homometric(al)s that can be of value to assessment user to the appropriateness (i.e. assessment certain architectures is to support payload intensive user or support signalling loads intensive user) of certain architectures.SGW can calculate the average throughput within each S1 carrying life-span, i.e. " T0=P0/ (t1-t0) ", " T1=P1 (t3-t2) " and T2.SGGW can also calculate the feature of the standard deviation being similar to Tn sequence etc, or it even can calculate the feature according to packet distribution (the such as how receiving) derivation in one of S1 carrying life-span according to the packet belonging to P0 in the time period of t0 to t1.

As example, if SGW sends the load attribute of the payload amount that instruction sent within a time period, and SGW for the first time this load attribute to be sent to MME be time t6 in Fig. 10 at, then as example, it is Ptotal=P0+P1+P2 that the payload that MME can obtain is measured.MME may have the information of instruction t0, t1, t2, t3, t4 and t5.But, MME may not have except to the user communications signals belonging to Ptotal determined by business relate to the information that the mode of each time period is relevant in addition to any information so that the data that can derive are fewer than the data that the full view having from SGW is derived.But increase the amount of initial data that SGW sends to MME or the frequency increasing transmission data is possible, but this is with the important cost of additional signaling as cost.

As example, MME may determine that signalling loads, the ratio of the payload tolerance Ptotal to build and receive, wherein, it is also contemplated that to time ti.Additionally, MME can by use at MME can signalling loads information participate in computational load attribute.In such a case it is possible to provide effective degree of loading amount to MME, MME can carry out computational load ratio based on this.

Figure 11 shows the figure of the network entity repositioning process demonstrated in following layout, in this arrangement, MME1105 defines the embodiment of network controlling entity, presents UE1101, eNodeB1103, SGW1107, SGW1109 and PGW1111 of the embodiment that form respectively network entity in this layout.

In step 1, UE1101 sends non-access layer information to MME1105, with instruction service request.This service request can trigger according to 3GPPTS23.401 standard.In step 2a, MME1105 sends message to SGW1107, with the request of instruction amendment carrying.MME1105 is responded in step 2b by SGW1107 with the carrying response revised.After step 2b, SGW1107 has established the S1 carrying such as arriving eNodeB1103.Afterwards, user subject 1101 sends payload to the SGW1107 processing user communications signals, and described user is associated with UE1101.As example, SGW1107 can forward this payload to PGW1111.Thus, in order to payload is transmitted, carrying can be set up during a time period.

Afterwards, in step 3a, can send release access bearer request from MME1105 to SGW1107, SGW1107 can send release access bearer response to MME1105 in step 3b.The request of release access bearer and response can be triggered by the tracking area update process with services network entity change according to such as 3GPPTS23.401 standard.Thus, it is possible to initiate and perform for being selected for processing further the network entity repositioning process of the SGW1109 of user communications signals.Afterwards, in step 4, user subject 1101 can send TAU request to eNodeB1103, wherein it is possible to perform the transmission of other message according to 3GPPTS23.401 standard, to set up the connection for new, selected SGW1109.Afterwards, new (i.e. selected) SGW1109 receives user communications signals (such as, payload) from user subject 1101, and forwards this payload to such as PGW1111.

According to the signaling process shown in Figure 11, SGW can use " release access bearer response " message, with to MME transport payload usage amount information, and MME1105 can use and have " tracking area update " process that service GW changes, with trigger from the SGW optimized for payload to the change of " new SGW " for signaling optimization, or vice versa as the same.

As example, signaling process shown in Figure 11 may begin at " the service request that UE triggers ", and its sole purpose is to illustrate that when setting up new S1 carries to SGW1107 and can start the payload/handling capacity of carrying use to be carried out counting until it discharges relevant example.But, this signaling process can also start from " the service request of network-triggered ".

According to embodiment, can apply 3G wireless access, wherein, MME1105 can be replaced by SGSN, and S11 interface can be replaced by S4 interface.In addition to LTE/MME/S11 situation or 3G/SGSN/S4 situation, use different messages or massage set can also be derived from SGW1107 to other embodiments of MME/SGSN1105 additional information transmission (such as, load attribute) herein.

Figure 12 shows the block diagram for processing the network controlling entity 1200 that the network entity of user communications signals is distributed.This network controlling entity 1200 can include the processing entities 1201 for obtaining load attribute, and this load attribute may indicate that the duty factor between payload and signalling loads.Processing entities 1201 is also based on load attribute to select network entity, concurrently plays network entity position fixing process, is used for processing user communications signals with the network entity selected by distribution.

Alternatively, network controlling entity can include the data storage 1203 for storing load attribute.It is furthermore possible to also provide receiver 1205 is for receiving load attribute from remote network entities (such as from home subscriber servers or from network entity).Additionally, network controlling entity 1200 can include transmitter 1207, for sending such as location or re-positioning request to selected network entity.

Figure 13 shows the block diagram of the network entity 1300 of the user communications signals for processing user.Network entity 1300 can include the communicator 1301 for transmitting user communications signals, and this user communications signals can be associated with signalling loads and payload.Network entity 1300 could be included for determining the processing entities 1303 of load attribute based on user communications signals, and this load attribute may indicate that the duty factor between payload and signalling loads.It is alternatively possible to provide data storage 1305 to be used for storing load attribute.

In order to send load attribute to network controlling entity (such as, the network controlling entity shown in Figure 12), network entity 1300 can include transmitter 1305.Transmitter 1305 can be the unit of communicator 1301, can be maybe single unit.Additionally, network entity 1300 can include receiver 1309, it is used for receiving such as user communications signals.Receiver 1309 can be the unit of communicator 1301, can be maybe the independent unit communicated with communicator 1301.

Below, by about form respectively network entity 1200 embodiment MME or SGSN and about defining the SGW of embodiment of network entity 1300 to be illustratively described other embodiments.It should be appreciated, however, that unless otherwise specified, following example are generally applicable to any network controlling entity and any network entity.

According to some embodiments, it is also contemplated that user behavior.Thus, along with the voice mobile telephone system development to EPS (LTE/EPC) framework with wideband packet data, the difference of subscriber's behavior is likely to become problem, because possible needs process such as has quite large-scale different user groups, what kind of looks like regardless of the precise proportions of each group in these groups.Below, it is illustratively described different user's groups.

The user that the audio call of pattern is main can be used to form user's group by having " traditional " phone.No matter the availability of broadband, video flowing transmission or game on line how, it is contemplated that a large number of users keeps the audio call using every day their telephone plant to carry out minority.Assuming that there is average mobility (such as, during being on duty or doing shopping), it is expected to them and organize identical signalling loads by producing with any other user, and the most considerably less data service (such as based on IMS VoIP), if using CS rollback, even wholly without grouped data.

Can be formed another user's group by such as user as the LTE/EPC of mobile broadband technology, they can include the UE of the data card type of true individual, and in the case of using another equipment, these true individuals fall within previous group.These users can produce a certain amount of payload so that their signalling loads can become less ratio.In any case, due to the great majority in them and be not frequently used streaming application, they can discharge and set up radio bearer several times every day, such as, create some signalling loads on SGW.

Another user's group can be in conjunction with above-mentioned user personality.This group by definition, user can be put into one of above-mentioned group in payload rank and as far as possible little.

The user of equipment (such as digital device (digitaldivide)) can be fixed by the LTE as DSL (DSL) substitute and form another user's group, this LTE fixes equipment and does not have mobility, and has more payload owing to e.g. fixing work station relative to the notebook of main flow and smart phone.

Another user's group can be formed by the stationary machines (such as measuring equipment or safety alarm equipment) with low payload.They may not produce mobility load, but they are likely to be of the similar ratio discharging/set up signaling and real data payload about carrying.

Another user's group can be formed by the stationary machines (such as the Internet radio, TV) with high payload being associated with the payload of low signalling loads and increase.

Can by the most in the car or the mobile machine of both types in public transport form another user's group.It is embedded in certain type of clothes or equipment in other application having not known is likely to may belong to this user's group, due to mobility, it is associated with the extra load on MME, and owing to carrying is set up and reorientation, it has higher signaling request to SGW.

So that network knows the respective sets that user belongs to, it is possible to use such as IMEISV (International Mobile station Equipment Identity and Software Version number) identifies different types of equipment.This can allow to identify most M2M (mobile to mobile device), and the type (such as the smart phone basic telephone other to entry level of costliness, high-res display are to miniscope) being had based on equipment provides the valid conjecture to User Preferences.Further, it is also possible to use user to subscribe to, that manage such as operator, for selling different set meal this point to different user set.

Above-mentioned example is additionally operable to the people that user can be operation user subject is described, this user subject can be such as mobile phone or laptop computer or the machine comprising user subject or the machine being connected to user subject.Can identify user by user identifier, this user identifier is e.g. for identifying the IMSI of the subscriber of mobile communications network.Alternatively or additionally, user subject can be identified by user subject identifier (IMEI in such as mobile communication system).

The corresponding entity (such as access node, network controlling entity, the network entity of process user communications signals and/or central data store) user identifier and/or user subject identifier can being transferred in communication network, to identify user's (correspondingly identifying user subject) at the corresponding entity of communication network, particularly obtain the load attribute being associated with specific user or user subject.Such as can adhere to (Attach) via the 1a in Fig. 1 or Fig. 2 and send user identifier from user subject 101 to access node 105, and can send the user identifier of identical user identifier or correspondence to network controlling entity 107 via 1b attachment, network controlling entity 107 and then via 1c attachment, the user identifier of the user identifier received or correspondence can be sent to central data store 109.The relation between described user identifier and the user personality intensive about signalling loads or payload that central data store 109 can be stored by analysis subsequently, determines that this specific user is generally to transmit signalling loads intensive communication signal or payload intensive communication signal.Such as, ID and load attribute value " P " and " S " (or according to alternative mark, can be 0 and 1, or vice versa as the same) can be correlated with by look-up table.According to the example of Fig. 1, thus central data store 109 receives the user identifier relevant to " P ", and according to Fig. 2, the user identifier received is relevant to " S ".According to the example of Fig. 3 to 7, the ID of the user of user subject 101 can be known by network controlling entity, can send request via (dotted line) to central data store 109 according to option a) network controlling entity.Normally, also it is in the case of option b), sends ID from network entity 113 to network controlling entity 107 so that network controlling entity 107 is suitable to, for the user communications signals corresponding with user identifier, initiate repositioning process.In a similar fashion, the replacement or supplementary as transmission and processing user identifier, can transmit and process user subject identifier.

It is no matter which kind of in these mechanism above-mentioned, following subscriber (that is, user) can be there is: it is that signalling loads is intensive or any information that payload intensity is relevant that network does not have to these users.As example, following user can be there is: their behavior there occurs change after their purchase contract that day；And there is also following subscriber: they can have different behaviors at weekend in the middle of on weekdays, or has different behaviors from the office work time in vacation.For special time period, this user dynamically can be redirected to optimum and process such as payload intensity or the network entity of signalling loads intensive user signal of communication.

Embodiment as herein described can be realized in the 3GPPEPS framework as described in 3GPPTS23.401 standard.As example, the UE being attached to system can have at least one EPS carrying, such as default bearer, and have the possible additional EPS carrying that may be used for other PDN connection or other QoS characteristics.Although some EPS carrying has a feature activated all the time, but part carrying between UE and the first payload EPC entity (i.e. SGW) can not be and activates all the time.In order to preserve Radio Resource and allow LTE scalable to be enough to be used in project number user, can be at network releasing wireless loading of inactive period.According to the embodiment accessing scene about WCDMA, it is also possible to perform RB and RAB and discharge process.Additionally, RB and RAB release process goes for other accesses scene.
